' It is the objectI of; this invention to produce a spring i hinge that,shall be especially Well adaptedafor `useavith foldable awning supports,and which shall-besoconstructed-that ithe spring can readilybe-tensionedso, asto exertjthe force necessary iandasolthat the springcan readily be removedfand replaced by .another if-itshould break.

The above' .and other obj ects that. may become;apparent as thisdescription proceeds are attainedi bymeans =of a vconstructionand anarrangement of parts athat AXvillenow :be described in detail, and -forgthis purpose ref- 1 30 erence will be. had to the accompanying drawingin Whichithe preferredfembodirnent of the invention 'has :beenillustrated, and 'in -Which: Fig. llis a sidefelevationof a foldable 353yavv-ningsupport .showing theesaine in mextended position;

In the drawing reference numeral 1 rep resents the surface of a Wall toWhich a bracket 2 is attached by means of bolts 3.' Securedto-fthefbracket is, an arm 4, which is formed from tivo tubular memberstelescopically con necte'd,the lsmaller of the tivo members has `beendesignated by Jreference numeral 5. Se-

cured to the outer end of member 5 is a hinge member 6. \Member 6 has ashank portion '7 'that extends into the end of the arm 5 and .60

isconnected to the latter by means of rivets '8. That part of the hingemember that projects beyond the arm isprovided Witha cenytralopening 9.Luge' 10 extend from one side iofthe upper and lower parts of the hinge.05

member and these lugs are perforated for the reception'of a pivot pin orbolt 11. The end ofthe hinge member has a projecting portion 12 that isperforated for Vthe reception of'a screw 13 that is held ink adjustedposition by 7 means of la lock nut 1liV and which serves as a stop.Reference YWill vbe made hereinafter to thisstop yand thefunction thatit performs.

T he other arm 15 ofthe support has a hinge vmember'l secured toit. Thishinge member lhasa slianlr17'tliatextends into the arm and isheld inplace by means of rivets 18. rlhe end ofthe secon-d hinge. member isprovided -Witlr fingers y19 that overlapV the lugs'l() in the mannershown in Fig. 2. The fingers 19 may ,80 either be located-between thelugs 10 as shown in the drawings, or, on the loutside of the lugs .asrmay be considered to be most desirable.

' The ingersz19 are provided with openings for the reception ofthe pivotpin 11 and When ..85 the parts are assembled,y hinge members 6 and d6can rotate with respect to each other about .the aXis of the pivot pin.--nected to the pivot pin is a cylindrical sleeve Rotatably con- QOithatis providedl at one end with an out-'L90 .wardly extending flange 21.This flange has plurality of notches 22 .and radial openings '23. Thesleeve is provided With a longitudiynally extending groove or slot 24for the re ception vof the inwardly bent end 25 of the 95 spiral-.spring26. rQlhe other end of spring 26 isprovided with a hook portion 27 thatengagesa bolt 28 securedto the hinge mein- .bera-6 all as. shown iiiFig.4.' The spring is .tensioned by lrotating the sleeve and when le f

the proper tension has been given to the spring, the pawl 29, which isconnected with the hinge member 16, is moved over into one of thenotches 22, and serves to hold the sleeve against rotation. The springis applied to the members and tensioned so as to produce a force thattends to move the hinge member 16 against the head of the bolts 13,which therefore serves as a stop to limit the relative rotation of thearms in one direction.

Secured to the outer end of the arm is a wooden bar 30, to which theawning is attached. Since this invention relates to the hinge, theoperation of this awning` support will not be described in detail, asthis is not necessary for a proper understanding of the invention.

It will be seen from the above description that the spring hinge thathas been shown on the drawing and described above is of a simple andsubstantial construction and provided with means for adjusting thetension ot the spring so as to get the best operation. If the springbreaks it can be very easily replaced, as all that is required is thatthe pivot pin 11 be removed so that the broken spring can be taken offand a new one put in place. When the tension of the spring is adjusted,a steel bar is inserted in one of the openings 23 and the sleeverotated. The pawl 29 can be moved about its pivot into and out ofengagement with the notches 22 and when the spring has been properlytensioned, it is held in tensioned condition by means of the pawl asabove described.

The base 31 of the bracket is provided on its opposite edges withnotches 32 through which securin bolts may pass, it is also provided atits top and bottom with projections 33 that hav-e perforations 34. Whenthe brackets are fastened to narrow vertical supports, the securingbolts pass through openings 34, but when the support is wide enough topermit it, the securing bolts pass through notches 32..,4
